some, said guide being formed in. the usoei iatch guard 6 of the much tic'ular construction of main yarn feed is not essential, however. so long as said feed is mounted upon the low 1* 3. The normal position of the lever 3, shot is to say, the position assumed by it when the singie yarn is being fed to the needles, is that shown in Figs. 1 and 3, this position being determined by contact of the resrwardly extending arm (225 107mm it may concern:

Be it known thee we Boomer S. Pmnurs fiIiNi BEKJARMLN H.

Iri onnted upon the rd 1 by means of :1 pivot pin 8 is an arm whose upper end hears upon the rearwc 'aiiy extending aim of :1 supplementary yarn feeding lever 10 whose forward or feeding arm plays in a. recessed portion of the latch guard 6, the contact surface of the rear arm of said lever 10 and the arm 9 being" so formed that, as said arm 9 is pushed forwardly in the ciii'ecision of the arrow 2: Fig. 1, is xvii aise the rear arm o e iever 10 and depress the forward arm is same so as to bring the yarn feo thereby into position to be fed to the needles of the machine, shown in Fig. 4,-moveof the arm 9 in :1 direction the reverse of that indicated by the arrow a: permitting the rear arm of the lever 10 drop and its forward arm to rise so as to carry fiche yarn I fiiereby our. of feeding position in re ,osiery is a common "oracspcci; to the needles, as shown in Fig. 1. empioy. in knitting certain A coiieci spring 11 connects a pin 12 on the a singic yarn. as for instance one 10 and a pin 13 which projects from nd. in k 'n other ports or the she standard 1 through a segmental 510$ 14 do combine "with said cotton yarn. is ihe arm 9, so shot it does notinerferewith oi different material, such as silk. .ree swinging movement of the letter, i silk. in ponions the rendency of the spring 11 being to im- 1 the .onhic yarn 1 downward movement to the rear arm 10 10 presi the second 0 of she lever 10 and rearwelrci movement to yin-n on the surface of she arm 9 owing to the cam-like action of object of our invent'on i the contact surfaces of said lever and arm.

When the lever 15 is-moyed in thedirec tion of the arrow it will contact with the back of the arm 9 and will move the same from the position .shown in Fig. 1 to that shown in Fig. 4, thereby shifting the supple mentary yam feeding lever 10 from the inoperative position shown in Fig. 1 to the operative position "shown in Fig. 4:. In order, however, to insure the application of the supplementary yarn to the .needles so; that it will lie upon the face of, the fabric, We find that when the supplementary yarn feed ismoved to feeding position the main yarn feed should be moved away fromthe normal position occupied by it when the.

main yarn alone is being fed to the needles, and we therefore provide for .liftingsaid main yarn feed slightly when the supplementary yarn feed is lowered into operative relation to the needles, said lift being eilected by means of a cam 17 (Fig. 3) on the leyer 15, which cam, as saidlever 15 is moved in the direction of the arrow 3 acts upon the rear arm of the lever 3 to depress the same and thereby to lift the outer arm of said lever carrying the main yarn feed, as shown in Fig. 4, the lever 3 resuming its normal position when the supplementary yarn feed lever lOis raised to inoperative position, as shown in Fi g. 1, when the lever 15 is swung in "a direction opposite that indicated by the arrow in Fig. 2. By this means the application of the supplementary yarn to the needles is at a point so much below that of, the main yarn as to insure .the

presence of the supplementary yarn on the face of the knitted web.

' We claim: D

1. The combination in a plating device for knitting machines of the main and supplem'entary yarn feeds, with means for moving the shpplementary yarn feed into. and

out of operative relation to the needles, Ineans for retainin the main yarn feed always in feeding position in respect to the needles, and means for shifting the position of the main yarn feed when the supplementary yarn feed is moved into feeding position.

2. The'combination in aplating device for knitting machines of the main yarn feeding lever and supplementary yarn feeding lever,

means for retaining the main yarn feed always in feeding position in respect to the needles, an actuating lever, and means whereby said actuating lever is caused to .move the supplementary yarn feeding lever from inoperativeto operative position and at the same time to shift the main yarn feeding lever from its normal feeding position to an abnormal feeding position.

3. The combination in a plating device for -knitting machines of the main yarnfeeding lever. and the supplementary yarn feeding lever, means for retaining the main yarn feed always 111 feeding position in respect to the needles, an actuating lever having a cam for acting upon the main yarn feeding lever to move it from normal to abnormal feeding position, and means whereby the movement of the actuating lever is transmitted to-the supplementary yarn feeding'lever to move the. same from inoperative to operative position. v
